Gingivitis
It is the most common cause of swollen gums. It’s a gum disease that causes your gums to become irritated and swollen. Many people don’t know they have gingivitis because the symptoms can be quite mild. However, if it’s left untreated, gingivitis can eventually lead to a much more serious condition called periodontitis and possible tooth loss.
Gingivitis is most often the result of poor oral hygiene, which allows plaque to build up on the gum line and teeth. Plaque is a film composed of bacteria and food particles deposited on the teeth over time. If plaque remains on the teeth for more than a few days, it becomes tartar.
Tartar is hardened plaque. You usually can’t remove it with flossing and brushing alone. This is when you need to see a dental professional. Tartar buildup can lead to gingivitis.
